10 Rare Pokémon You Only Had ONE CHANCE To Catch

Fancy getting your hands on a Chansey that knows the "Wish" move?

Well my friend there's a fat Chansey of that happening legitimately, as this might well be one of the most sought-after Pokémon even to this day. Thanks to trainers wanting to breed the skill and turn this egg-carrying cuddly into a fighter that will absolutely scramble their opponents.

While online forums might be rife with people looking to trade such a Pokémon, about 99% of these are hacks, seeing as the only true way to achieve this was to collect an Egg code from Pokémon New York in 2004 - something only available for a month at the end of 2004.

It's not clear if the Eggs were identified as they were given out, but they were limited to one egg per day across this time period, suggesting that of the six Pokémon that could hatch from them, they were randomized.

Even if you did attend the store every day, you might not have walked away with this Wish Chansey, putting it at the top of our list.
